NITED STATEs PATENT OFFICE.
JOSEPHINE L. THROOP, OF GREENOASTLE, INDIANA.
UNIVERSAL ADJUSTABLE LIFTER.
SPECIFICATION forming part of Letters Patent No. 487,105, dated November 29, 1892,
Application filed April 25, 1892- Serial No. 430,653. (Model-l To all whom it may concern:
Be it known that I, JOSEPHINE L. THROOP, a citizen of the United States, residing at Greencastle, in the county of Putnam and State of Indiana, have invented a new and useful machine or universal adjustable lifter for the purpose of handling curtains, portieres, picture-frames, or other similar articles when for any purpose it is desired to lower or replace them.
The following description will make the construction of myinvention suflicien tly clear.
Figure 1 represents the apparatus when opened out at full size and length ready for use. Fig. 2 represents it closed up and shortened when not in use.
In Fig. 1 the rod A, of suitable size and length, forms the handle. This passesthrough a neatly-fitting hole B in the block 0 and may be held in the required position by the set-screw D. The rods E E are hinged or joined to the block 0, permitting a motion of their outer extremities toward or from each other, thus varying the distance apart of the prongsF F, which terminate the outer ends of rods E E. These rods are held at the required angle by means of the adjustinglink G, com posed of tWo members, the .outer ends of which are pivoted to the rods at H H, the inner ends being joined together in such manner as to allow a swivel movement and held in proper position by the set-screw I. This set-screw I being loosened permits the two members of the adj usting-link to form with each other an angle more or less acute or obtuse, thus bringing together or separating the prongs F F, the whole when the screw is tightened being held in position. The proper length is obtained by sliding the rod A through the block 0 and tightening the set-screw D.
The rods E E must be attached on one side of block C in a way to prevent interference when the block C is passed along the rod A or handle, as in closing.
The same letters refer to like parts in Fig. 2.
I am aware that a single rod with 2. prong has been in common use for the purpose of lowering or replacing articles out of ordinary reach, and therefore do not claim this feature; but
What I do claim as my invention, and desire to secure by Letters Patent, is
In combination, a block adapted to be socured to a handle, rods pivoted to the block, prongs on the outer ends of the rods, an adjusting-link pivoted to the rods, and means for securing said link when adjusted, substantially as set forth.
JOSEPHINE L. THROOP.
